Hot Water Guys

What Hot Water Guys does

Hot Water Guys is a privately held, Houston-based specialty trade contractor founded in 2004 by Tom Massimin and Kenny Browning. The company focuses exclusively on water heating technology — installation, repair, and maintenance of both traditional tank and modern tankless water heaters — rather than operating as a general plumbing service. It is a factory-authorized service center for ten major water heater brands, including Rinnai, Navien, Rheem, Noritz, Takagi, A.O. Smith, Stiebel Eltron, Bosch, Vesta, and Whirlpool, which enables it to handle warranty claims across the product spectrum.

The company's service portfolio covers tank and tankless water heater installation, repair, and maintenance for both residential and commercial customers, with additional offerings in whole house water filtration (activated carbon filters, water softeners, PFAS specialty filtration). Its technical specialization includes handling Houston's hard water conditions (12-17 grains per gallon) through scale-prevention approaches and hard-water-specific descaling protocols. Installations range from $2,500-$4,500 for tank units to $4,200-$8,000 for tankless systems, with repairs priced from $165-$600 depending on component.

The business operates a direct-to-consumer go-to-market model with free over-the-phone estimates (832-673-0909), positioned as an alternative to high-pressure plumbing industry sales tactics. It serves a 7-county service area across the Greater Houston metropolitan region (Harris, Galveston, Brazoria, Fort Bend, Montgomery, Liberty, and portions of Waller and Chambers Counties). The company is bootstrapped and founder-owned, with no disclosed external funding or institutional ownership, and has accumulated over 1,400 five-star Google reviews reflecting 20+ years of operating history.
